This study examined the attitudes toward and knowledge about suicide of gifted and unselected high school students. A questionnaire was developed which included items about societal factors related to suicide, warning signs of suicide, general knowledge of and attitudes about suicide, personal knowledge about suicide, and the intervention strategy or action an adolescent might take if a friend confided a suicidal intent. In general, gifted students did not appear to have more knowledge about suicide and had similar attitudes to other students. Gifted students, however, were more likely to indicate that self would be the primary intervention person, whereas the unselected students ranked themselves as the fifth choice in providing intervention. The responses of the 12 students who had actually attempted suicide were not significantly different from those of their respective groups. Other findings included: more than 50% of both groups knew someone who had attempted suicide; more than 20% had seriously considered suicide themselves; major reasons suggested for attempted suicide were problems at home and drugs and alcohol; over 70% believed that depression, withdrawal, and giving away possessions were signs of pre-suicidal behavior; about 90% believed loneliness increases suicide risk; and no students indicated they would take no action if a friend confided suicidal intentions.
